add redirect codes to lb target group health check

• Add commonly used redirect codes to health check

There are many circumstances that a healthcheck on / (root) would need redirect to be detected as a healthy state.

I'm fine with that. If we want our methodology to ONLY allow 200's in the future and just standardize a standard health check route into our apis that guarantees a 200 on healthy state then we'll do that.
